Jewish POWs were separated in special POW camps for Jews. They were told that Finnish people hate them and they are to be transferred to Germany. But the intent changed and only Communists were actually transferred to Gestapo. Other Jews were allowed to contact with representatives of Finnish Jewish community.

Finnish authorities installed special ethnic-cleansing conentration camps for Slavic-speaking inhabitants of Karelia and other occupied territories.

I wonder whether the Jewish civilians were treated separately of Slavic population.

Most likely not. They were a German ally, but never under the control of Germany like most of their other "allies" that engaged in such behavior. They just happened to be fighting Russia, and Germany was the only ally avilable (and even then, only after Barbarossa. They were on their own before that).

@Anixx This Wikipedia article contains enough material for an answer. I did not write it as I have not much to add and don't want the question to receive less attention. en.wikipedia.org/wiki/…

Do you mean "persecution", rather than "prosecution"?

Jewish men served in the Finnish military like all the other Finnish men (and some volunteers), many Jewish women served as volunteers in the Lotta Svärd organization or as nurses etc. The civilians continued their lives as best as they could, considering the fact that the country was at war against the Soviet Union.

Edit: One should first know if there were any Jews in those areas, alive. The best guess is that only a small number if any, considering Stalin's Purges in the area (and there were not that many of them in the first place). If they were Russian Jews, they would have been treated as other Russians.

While this sounds plausible, it would be improved by sources/citations.

Welcome to StackExchange! This seems like the beginning of a good answer but the fact that you've needed to make so many clarifications in the comments tells me that it requires editing.

Please, provide references for statements such as " Thousands of Finns living in that area were executed in the 1930s". (I don't need convincing that Stalin was a monster, a criminal, a genocidaire, you name it - still, statements such as the one I quoted must be backed up by references, otherwise we are not really doing history).
